Comparison of Sacrificial Anode and Impressed Current Cathodic Protection Methods using Electric Resistance of Mild Steel 低碳钢电阻牺牲阳极和外加电流阴极保护方法的比较
Mohammad Hanif, Bijoy Harun, M. Islam, N. Mohammad, K. Ahmmed
Corrosion is a universal process occurring due to chemical reactions between metal and the environment. Corrosion of the metal can be controlled by numerous methods, and among many controlling methods cathodic protection is noteworthy. Cathodic protection of metal consists of two methods namely impressed current method and sacrificial anode method. Both methods deal with the transportation of electrons either receiving or donating from or to the metal or to the environment. Again, the electric resistance of a metal piece is inversely proportional to this cross-sectional area. If a metal bar corrodes fast, then its cross-sectional area reduces rapidly and its electric resistance increases highly. So, the relation between corrosion and electrical resistance of the metal is a helpful parameter to determine the corrosion rate. In this paper, we determine the corrosion behavior of mild steel exposed to different concentrations of ionic liquid to compare the possible variations in the corrosion protection techniques for the mild steel used.
腐蚀是金属与环境发生化学反应而产生的一种普遍现象。控制金属腐蚀的方法有很多,其中阴极保护是值得注意的。金属的阴极保护包括外加电流法和牺牲阳极法两种方法。这两种方法都涉及电子从金属或环境中接收或提供的传输。同样,金属片的电阻与横截面积成反比。如果金属棒腐蚀快,则其截面积迅速减小,电阻急剧增加。因此,腐蚀与金属电阻的关系是确定腐蚀速率的一个有用参数。在本文中,我们确定了低碳钢暴露在不同浓度的离子液体中的腐蚀行为,以比较所使用的低碳钢腐蚀防护技术的可能变化。

Z. I. Borshon, A. Nafis, A. S. M. Badruduzza, M. K. Kundu, M. Sarkar
This paper aims to the study of security in wireless transmission system through Weibull fading single-input multiple-output multicast channels considering multiple receivers and eavesdroppers. At first, the analytical expressions for the probability of non-zero secrecy multicast capacity and the ergodic secrecy multicast capacity are derived in closed-form to illustrate the numerical results. Then the closed-form expression for the secure outage probability is obtained to examine the secure outage behaviour. Finally, a comparison between Weibull and Rayleigh fading channel is presented to demonstrate the impact of Weibull fading parameter on the secrecy performance of the proposed scenario.

Data compression is the reduction of bit or actual size of data by eliminating the repetition of identical sets of data bits to achieve fewer bits than the primary one. Character encryption is a famous time period of statistics compression that includes an everyday sample of records individual with a few affable encoding formulations. This encoding is a pastime of corresponding encoding approach that encompasses character characters, dolled up with extraordinary sorts of data and emblems. Data compressions expand over a large field of citation including data storage, database technology, and data transmission. In this paper, a statistics compression method denoted as Lossless Bit Isolation (LBI) has been implemented which honestly manifested on a character encoding technique. These isolated characters have found using set, sub-set, and static dictionary. Similarly, for assimilating the outcome of LBI two most well-liked algorithm terms LZW and Huffman are used.

Differential Embedding and Chirikov Map based Image Watermarking in Transformed Domain 变换域差分嵌入和基于奇里科夫映射的图像水印
Syeda Saida Khadeeza Nawrin, C. Saha
With the increasing growth of technology, image security is hampering day to day. Now a watermarking technique which ensures security with less computational effort is the best solution. In this paper differential embedding and chirkov map based image watermarking in transformed domain is proposed. Here, Chirikov map is employed for scrambling the watermark providing security to the method. 2nd level DWT is applied to the host image and the middle band coefficients are chosen to maintain balance between imperceptibility and robustness. These coefficients are DCT transformed for energy compaction and zigzag scanning is performed to cluster the highly correlated coefficients. The concept of differential signaling is used to embed the watermark into the highly correlated coefficients of the host image. The use of different strength factor as secret key and control parameters in Chirikov map will ensure security. At the end section, NCC, MSE and PSNR is calculated as performance parameter to evaluate this method and comparison with the existing method is also discussed and our proposed method shows robustness and imperceptibility against a numbers of image processing attacks.
随着技术的日益发展,图像安全问题日益严重。目前,以较少的计算量保证安全性的水印技术是最好的解决方案。本文提出了一种基于变换域差分嵌入和chirkov映射的图像水印方法。本文采用奇里科夫映射对水印进行置乱,保证了算法的安全性。对主图像进行二级小波变换,选择中间带系数,以保持不可感知性和鲁棒性之间的平衡。对这些系数进行DCT变换进行能量压缩,并进行锯齿形扫描对高相关系数进行聚类。利用差分信号的概念将水印嵌入到主图像的高相关系数中。在奇里科夫图中使用不同的强度因子作为秘钥和控制参数,保证了其安全性。最后,计算了NCC, MSE和PSNR作为性能参数来评估该方法,并与现有方法进行了比较,我们提出的方法对许多图像处理攻击具有鲁棒性和不可感知性。

Md. Aslam Mollah, Md. Yousufali, Md. Rifat Bin Asif Faysal, Md. Abdul Mazid, R. Marma
We propose a simple rectangular lattice microstructure optical fiber (MOF) based plasmonic refractive index (RI) sensor for analyte sensing having RI range from 1.35 to 1.40. Sensitivity analysis of the suggested RI sensor is done by finite element method (FEM). Simulation result shows that amplitude and wavelength sensitivity of the presented RI sensor can reach 1200 RIU-1 and 12,000 nm/RIU, respectively, while corresponding resolution is obtained of 8.33 × 10-6 RIU. In addition, deposition of gold film outside the MOF structure makes this sensor practically feasible as well as keeps the confinement loss very low. Due to these advantages, the suggested sensor can be used in analyte sensing application.

Abu Saleh Musa Miah, M. Islam, M. I. Molla
To assist disabled people by controlling an external system by using motor imagery (MI) is a common applications of brain computer interface (BCI) field. This paper we focused on an experimental comparison of covariance matrix averaging ways of EEG signal and EEG classification of two types of MI tasks $(right-hand^{ast}$ foot and right-hand*left hand). Indeed averaging covariance matrices of EEG signal might be a used in brain computer interfaces (BCI) with common spatial pattern (CSP) method. Structured into trials is a usually paradigms of BCI which we have a tendency to use this structure into account. In addition, covariance matrices with non-Euclidean structure should be consideration likewise. We review much method for averaging covariance matrices in SVM from literature and observe through the experimented result using publicly available four datasets. Our experimental result show that for the case of averaging covariance matrices using Riemannian geometry with small dimension feature issue improve the classification performance. Our result shows the performance increase (2% >performance), but also the limit of this method once the increase feature dimension.
利用运动意象(MI)控制外部系统来辅助残疾人是脑机接口(BCI)领域的一个常见应用。本文主要对两种MI任务(右手^{ast}$ foot和右手*左手)的脑电信号协方差矩阵平均方法和脑电信号分类进行了实验比较。用共空间模式(CSP)方法对脑机接口(BCI)中脑电信号的协方差矩阵进行平均是可行的。结构化试验是脑机接口的一个典型范例我们倾向于使用这种结构。此外,非欧几里得结构的协方差矩阵也应予以考虑。我们从文献中回顾了支持向量机中协方差矩阵的平均方法,并通过公开的四个数据集的实验结果进行了观察。实验结果表明,对于具有小维特征问题的黎曼几何平均协方差矩阵,可以提高分类性能。我们的结果表明,随着特征维数的增加,该方法的性能有所提高(> 2%),但也存在局限性。

Multi-Camera Tracking System Applications Based on Reconfigurable Devices: A Review 基于可重构器件的多摄像头跟踪系统应用综述
Farhana Binte Sufi, J. Gazzano, Fernando Rincón Calle, Juan Carlos Vallejo López
Real-time video image processing requires video compression techniques. Efficient Motion Estimation (ME) and Motion Compensation (MC) algorithms and their successful hardware implementation are the key to video compression. Work on developing and implementing efficient ME and MC algorithms for multi-camera systems is ongoing. The low power consumption yet high speed of Heterogeneous Reconfigurable Devices such as Field Programmable Gate Arrays (FPGA) can be suitable for implementation of real-time optic flow computation using multi-camera systems. This paper focuses on a search into the current state-of-the-art for multi-camera motion tracking. It has been found the tracking systems mainly focused on people and vehicle tracking in both indoor and outdoor conditions, tracking under occlusion, tracking for surveillance, single and multi-view tracking, etc. The review search also found use of multi-camera tracking in the medical sector, such as multi-camera tracking systems for respiratory motion tracking. Research on this field has not been explored much and this holds possibilities for further work.

Development of a Microprocessor Based Smart and Safety Blind Glass System 基于微处理器的智能安全盲玻璃系统的研制
Md.Tobibul Islam, Mohiudding Ahmad, A. S. Bappy
In this paper, we present a unique microprocessor-based wearable glass security system for human beings who are blind or visually impaired. People who are visually impaired face hard to communicate efficaciously with their environment. They always depend on other people. Sometimes they fall into a lot of troubles when on foot in the road, field, marketplace, bus stand, railway station and so on. So, making sure their safety is very important to us. Imparting the blind person the safety information about their surroundings and family members are the goals of the smart glass safety system. This paper offers a correct and dependable real-time monitoring system using global positioning system (GPS). This smart glass device will help blind humans attain improved independence and freedom in the indoor and outdoor environment. We have proposed a smart glass application to address the safety threat to blind people and give security information to the family members of the blind man. The proposed prototype system is based on a Raspberry pi 3 model B and NEO-6M GPS module. Our proposed system is good, low cost, highly efficient and user-friendly.
在本文中,我们提出了一种独特的基于微处理器的可穿戴玻璃安全系统,用于盲人或视障人士。视障人士很难与周围环境有效沟通。他们总是依赖别人。有时他们在道路、田野、市场、汽车站、火车站等步行时遇到很多麻烦。所以,确保他们的安全对我们来说非常重要。让盲人了解周围环境和家人的安全信息是智能玻璃安全系统的目标。本文提出了一种基于全球定位系统(GPS)的准确可靠的实时监测系统。这种智能玻璃装置将帮助盲人在室内和室外环境中获得更好的独立性和自由。我们提出了一个智能眼镜应用,解决盲人的安全威胁,并为盲人的家人提供安全信息。提出的原型系统基于树莓派3模型B和NEO-6M GPS模块。该系统具有性能好、成本低、效率高、操作方便等特点。

People who are visually impaired face hard to communicate efficaciously with their environment. They always depend on other people. Sometimes they fall into a lot of troubles when on foot in the road, field, marketplace, bus stand, railway station and so on. So, making sure their safety is very important to us. Imparting the blind person the safety information about their surroundings and family members are the goals of the smart glass safety system. This paper offers a correct and dependable real-time monitoring system using global positioning system (GPS). This smart glass device will help blind humans attain improved independence and freedom in the indoor and outdoor environment. We have proposed a smart glass application to address the safety threat to blind people and give security information to the family members of the blind man.
